Under Washington law, you can clean up a site contaminated by hazardous waste with or without Ecology's supervision.
If you choose independent cleanup, you can clean up without our input, or you can request fee-based assistance through our Voluntary Cleanup Program. You can also request one of Washington's other technical assistance programs: Pollution Liability Insurance Agency's Program's (PLIA's) Heating Oil Technical Assistance Program (HOTAP) or PLIA's Petroleum Technical Assistance Program (PTAP). Use our Agency Determination Checklist to determine which one your site is eligible to use.
If you're cleaning up a heating oil site, please note that these are now managed under PLIA's HOTAP. If you have an eligible non-heating oil petroleum tank system site, these cleanups are managed under PLIA's PTAP. For more information about PLIA's programs, please contact firstname.lastname@example.org or 1-800-822-3905.
For all cleanups that we supervise, cleanup schedules are negotiated with us and cleanup plans go through public review and Ecology approval. There are two options for Ecology-supervised cleanups. The options are based on the type of legal agreement you enter into with the state and whether your liability is settled. A consent decree settles your liability to the state and provides protection from third-party contribution claims, while an agreed order does not.
